I-PTFE i-high-temperature yokushisa ilaphu yokubhaka i-mats inika iingenelo ezine eziphambili: ukusebenza okungeyona intonga (akukho mafutha okanye umgubo ofunekayo, i-pastries e-ethe-ethe ikhupha ngokucocekileyo), uluhlu olubanzi lobushushu (-70 ° C ukuya kwi-260 ° C, ikhuselekile kwi-oven ukuya kwisikhenkcisi), ukusetyenziswa kwakhona (amawaka emijikelo, kulula ukuyicoca), kunye nokuqhuba ubushushu (ukuthintela ukutshisa, ukulungelelaniswa okumdaka). I-FDA yomgangatho wokutya iyahambelana, bakhupha iphepha lesikhumba kwaye bagqithise iimethi ze-silicone ngokugqithisela ubushushu obungcono kunye nokucoleka komphezulu.

Ilaphu le-PTFE lobushushu obuphezulu libalulekile kwishishini lempahla edibanisayo. Usetyenziso oluphambili: amabhanti okuhambisa angenamthungo angenasiphelo koomatshini bokudibanisa abaqhubekayo (bathintela ukuncamathelisa okutshisayo okunyibilikayo, ukuhambisa okungenamibimbi), isigqubuthelo esinganamatheli kunye nelaphu lokugquma lobushushu obucaba (ukhusela iipleyiti kungcoliseko oluncamathelayo), amabhanti okuhambisa amachaphaza okuncamathisela/umgubo wokuncamathisela ngexesha lokuncamathisela. ukomisa / ukuthambisa), kunye nezihlangu zezihlangu zentsimbi zokucofa isampulu. Ukutyeba ukusuka kwi-0.13mm (i-padding elula) ukuya kwi-0.55mm (iibhanti zokuhambisa ezinzima).

Ilaphu le-Fiberglass ukucutheka kwe-thermal ngoyena nobangela wokungazinzi kwetape ye-PTFE. Kubushushu be-PTFE sintering (360-400 ° C), uxinzelelo lokulukwa olushiyekileyo luyakhululwa. Ukuba ayinqandwa, ilaphu liyancipha; ukuba unqandekile, uxinzelelo olufihliweyo luvalelwe, lubangela ukuncipha kamva ngexesha lokunyathela (150-200 ° C) kunye nokushisa kokuphela kokusetyenziswa. Isisombululo: sebenzisa i-fiberglass esele ifakwe ngaphambili kunye ne-<0.5% shrinkage kwi-400 ° C, ukuphelisa uxinzelelo olushiyekileyo ngaphambi kokugubungela.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inikeza uxhathiso lweekhemikhali ezikhethekileyo, ukumelana ne-acids concentrated (kuquka i-aqua regia), i-alkali eyomeleleyo (kwiqondo lobushushu begumbi), izinyibilikisi eziphilayo, kunye ne-oxidizing agents. Ngaphandle: isinyithi esinyibilikisiweyo sealkali kunye nobushushu obuphezulu bekhompawundi yehalogen ihlasela i-PTFE. Umonakalo wokugquma ubeka i-fiberglass kwi-hydrofluoric acid kunye ne-alkali egxininiswe eshushu. Ubushushu obungaphezulu kwe-260 ° C bunciphisa ukuxhathisa. Kwiindawo ezininzi zeekhemikhali, ilaphu le-PTFE lihlala lizinzile kwaye lithembekile.

I-PTFE emulsion imregnation yelaphu le-fiberglass ifuna abancedisi abahlukeneyo ukufezekisa ukoleka okufanayo, ukuncamathela okuqinileyo, kunye neendawo ezingenasiphako. Izongezo eziphambili zibandakanya: ii-agent zokumanzisa (ukunciphisa ukunyanzeliswa komhlaba, ukuphucula ukungena), i-thickeners (ukulawula i-viscosity kunye nobunzima bokugquma), abalawuli be-pH (i-emulsion yokuzinza kwi-pH 9-10), i-silane coupling agents (ukuphucula ukunamathela kwiglasi), i-filimi-forming aids (PFA / FEP ye-sintering), izigcwalisi ezisebenzayo (ukumelana nokuguga, i-deventroxt, i-developers, i-development conductivity) (ukoma kancinci). Ukukhethwa kuxhomekeke kwi-substrate kunye neemfuno zokusebenza.

Ilaphu lefiberglass eyandisiweyo (ilaphu lelaphu elikhulu) lahluke kakhulu kwilaphu eliqhelekileyo le-fiberglass kwisakhiwo somsonto. Ngonyango lwejethi yomoya yoxinzelelo oluphezulu, imicu yeglasi eqhubekayo yahlulwa, yahluzwa, kwaye igutyungelwe ibe yivolunous, intambo efana nomqhaphu. Oku kudala ilaphu elijiyileyo, elithambileyo eline-insulation ephezulu ye-thermal (i-air layers evaleleke), ukuhambelana ngcono, ukusebenza kakuhle kokucoca, kunye nokuphuculwa kokumelana nokukrazula / ukuguquguquka - ngexabiso lamandla asezantsi kancinci. Isetyenziselwa iigaskets ezinobushushu obuphezulu, ukusonga kwemibhobho, iingxowa zokucoca, kunye nezitywina ze-oveni.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) iphantse yangena kwikhemikhali, kodwa izinto ezithile zibangela ukubola phantsi kweemeko ezithile. Uhlaselo oluthe ngqo lwe-PTFE lwenzeka ngesinyithi esinyibilikisiweyo se-alkali (i-sodium, i-potassium), i-fluorinating agents eyomeleleyo (F₂, ClF₃) kumaqondo obushushu aphezulu, kunye ne-alkali eyomeleleyo etyhidiweyo ngaphezulu kwe-300 ° C. Ukonakala ngokungangqalanga kwenzeka xa i-hydrofluoric acid (HF), i-alkali egxininisiweyo eshushu, okanye i-phosphoric acid eshushu igqobhoza iziphene zokwaleka kwaye ihlasele i-fiberglass substrate. Kwinkonzo yeekhemikhali ezigqithisileyo, sebenzisa ifilimu ecocekileyo ye-PTFE ngaphandle kwe-fiberglass.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inokumelana nokuxhathisa ukothuka kwe-thermal ngaphakathi koluhlu lwayo lokusebenza oluqhelekileyo lwe--70 °C ukuya kuma-260°C. Iyakwazi ukunyamezela ukukhwela ibhayisekile kobushushu obukhawulezayo, umz., ukusuka kwi--50°C kwisikhenkcisi ukuya kumatshini wokushicilela oshushu wama-260°C. Amabakala ePremium ade aphumelele ukupholisa ngesiquphe ukusuka kwi-260°C ukuya kwi-10°C emanzini. Nangona kunjalo, ukothusa izinto ezivela kumaqondo obushushu angaphezu kwe-300 ° C (kufuphi ne-PTFE's 327 ° C melting point) kuya kubangela ukuqhekeka kunye nokuchithwa kwangoko. I-fiberglass substrate ibonelela ngokuzinza kwe-dimensional; I-PTFE yokwambathisa yinto ethintelayo.

Ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa kakhulu kushishino lweekhemikhali kwizicelo ezingundoqo ezisixhenxe: iigaskets zeflange kunye nelayini yombhobho (ixhathise i-acids eyomeleleyo/alkali), i-reactor kunye ne-tank linings (ithintela ukubola kwesinyithi, ukucoca lula), iingxowa zokucoca igesi enomhlwa (ukuya kuthi ga kwi-260°C), i-anti-corrosion expansion, i-anti-corrosion extensions ukubumba okuhlanganisiweyo, kunye nokusonga kombane/kwe-thermal. I-FDA kunye ne-UL amabakala akhoyo.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inika iingenelo ezine eziphambili njenge-anti-corrosion lining: inertness yekhemikhali (imelana ne-aqua regia, i-alkali eqinile, i-solvents), uluhlu olubanzi lobushushu (-70 ° C ukuya kwi-260 ° C ngokuqhubekayo, i-350 ° C peak), ukuzinza kwe-dimensional (<0.5 kunye ne-build-up, i-buildup, i-buildup, i-buildup, i-buildup, i-build up). Isetyenziswa kwimibhobho yekhemikhali, iinqaba ze-desulfurization, iitanki zokuchola, kunye nezixhobo zokutya / ze-pharma. Amanqaku e-FDA akhoyo.
